Island hopping on Sydney Harbour

Sydney Harbour is dotted with small islands, some of which can be accessed by visitors. Cockatoo Island and the much smaller Fort Denison were both Aboriginal fishing grounds before European settlement and both played a part in Australia’s convict history.

Fort Denison was known to Aboriginal people as Mat-te-wan-ye, meaning a steep rocky island, before it became a prison and defensive facility. It was nicknamed Pinchgut because convicts were held there in leg irons with rations of only bread and water. The Martello tower, completed in 1857, was built with 8,000 tonnes of sandstone.

Cockatoo Island is named after the sulphur-crested cockatoo, a large white parrot with a distinctive yellow plume. The island’s prison buildings are on the World Heritage list along with 10 other Australian convict sites. You can camp on Cockatoo Island in permanent tents, or stay in heritage buildings associated with the island’s past as a naval shipyard.

Shark Island, so-called because of its shark-like shape, is Sydney’s most popular picnic island with grassy areas to sit on, large trees offering shade and wonderful views of the harbour in all directions. Ferries from Circular Quay, near the Sydney Opera House, service all three islands.
